Walker won't answer questions about evolution, Obama

The Wisconsin governor is using the tried-and-true tactic to survive criticism over his refusal to answer questions about what he thinks about evolution and if he believes President Barack Obama is a Christian and a patriot. Instead, as his star rises among conservatives and he moves toward a 2016 presidential bid, Walker is insisting those questions are a media-manufactured sideshow -- and he'll have nothing to do with answering them.
